The two sites they compared were:

WhiteHatMedia.com & Smart-Traffic.co.uk

Note that SEOWizz is located in the UK and so if you attempt to find these same sites listed at the top of Google US, you won’t.  You’ll first have to visit Google UK and Bing UK and then do the same search for yourself.

What they did was compare the top SEO factors for any website and to what percentage it was the same or differed for each search engine.

Here’s the results and a breakdown of what they mean:

The Title Tag

Bing:  100% | Google: 100%

Regardless of which search engine, the title tag is still of primary importance.

Keyword Density

Bing: 3.8% | Google: 4.5%

This suggests that Google favors a little higher keyword density but not but much.

Prominence (where the keyword is located on the page the higher up on the page, the more prominence it is said to have.)

Bing: 52% | Google: 46.9%

Bing favors keyword prominence a little more than Google does.

Link Density (how many links are located on the page)

Bing:  2.7% | Google: 8.5%

In Google’s case, more links scored higher.

Link Prominence (where those links are located)

Bing: 0.9% | Google: 4.3%

Again, Google tended to favor a higher link prominence.

H1

Bing:  Y | Google: N

Bing taking them into account, Google wasn’t.

H2

Bing: N | Google: N

Neither of them taking into account H2 tags.

Meta Keywords

Bing: N | Google: Y

Interesting here.  Google seemed to take into account the meta keywords while Bing did not.

Description

Bing: N | Google: Y

Google using the description as a ranking factor, Bing not.

PageRank

Bing: 5 | Google: 4

For the sites compared, the site in the #1 position at Bing ranked a 5 whereas the site #1 in Google ranked a 4.

Off-Page Factors

Link Popularity

Bing: 8120 | Google: 19,700

Huge difference here!  Obviously Google taking into account the links pointing to the site.

Link Diversity (how many of the links come from different sites.)

Bing: 1.27% | Google: 3.04%

Again, Google the winner here.  By more than half.

“SEO” Anchors %

Bing: 45.8% | Google:  97.2%

Google taking into account by a very large margin the number of times the term “seo” showed up in the anchor text.

“Services” Anchors %

Bing:  29.2% | Google: 21.1%

Bing the winner here with them favoring the anchor % of “services”.

Domain Age

Bing:  5 Years 6 Months | Google: 2 Years 5 Months

Very interesting.  The site in the #1 position at Bing is considerably older than the site in the #1 position at Google.  This leads us to believe that age may not be as large of a factor as once believed.

Linking Pages

“seo” in body

Bing: 55.8% | Google: 100%

“services” in body

Bing:  67.4% | Google: 73.1%

“seo” in title tag

Bing: 4.7% | Google: 3%

“services” in title tag

Bing: 9.3% | Google: 1.5%

Of the “Linking Pages” section, it’s important to note that Google tended to favor sites that contained the keywords within the body of the linking site whereas Bing favored the sites that had the keywords within the title tag.

Average PR of Link

Bing:  2.4 | Google: 2.5
